Chief Executive Officer John Challenger said the layoffs appear to be prompted more by changes in technology and consumer demand than by an economic slowdown.

"The uptick in tech job cuts we saw in the first half of the year appeared to be due primarily to shifting trends in the computer and information technology industries, which are making it necessary for companies to alter business strategies, streamline operations and restructure their organizations," Challenger said.

"Technology firms have become particularly adept and nimble when it comes to adjusting to emerging trends," he said.
